Crandall Office Furniture’s Herman Miller Mirra 1 aftermarket stool gas cylinders have been constructed to meet original OEM chair specifications and are built to last.
A office chair gas cylinder is the height adjustment mechanism on the chair. The typical life span of a office chair gas cylinder is 4-7 years, depending on use and abuse. If failed, your chair will be left with limited or no height adjustment, however you can quickly and easily replace your broken Herman Miller Mirra 1 stool gas cylinder today.
Our Herman Miller Mirra 1 gas cylinders are made to fit all Herman Miller Mirra 1 chairs (does not work on the Mirra 2 chair).
This cylinder can successfully be used on a standard Herman Miller Mirra chair, to convert it to stool height, standing desk, sit-to-stand desk, or bar height. Also available is our full stool conversion kit (including foot ring) for the Herman Miller Mirra chair.
